The objective of this study was to develop review criteria to assess the quality of care for three major chronic diseases: adult asthma, stable angina, and non-insulin dependent diabetes mellitus. The results show the importance of a systematic approach to combining evidence with expert opinion to develop review criteria for assessing the quality of three chronic diseases in general practice. The evidence base for the criteria was often incomplete, and explicit methods need to be used to combine evidence with expert opinion where evidence is not available.
